MTU 12 V 4000 M73 x Operating Instructions Manual page 92

Simulation of power failure (emergency): SAT
1. Switch on fuel treatment system (→ Page 93).
2. Start engine (→ Page 85).
3. Run engine at idling speed.
4. Switch off pump (21) at switchgear cabinet (20).
Result: The engine-mounted fuel delivery pump draws fuel via bypass (2) directly from tank (24).
5. Check suction pressure at the engine-mounted fuel delivery pump.
Note: If the suction pressure is within the permissible limits and engine operation is satisfactory.
6. Operate engine at full load and monitor suction pressure.
Result: If the suction pressure is within the specified limits, simulation was successful.
